The Institute of Atmospheric and Cryospheric Sciences (ACINN) is one of the few university institutes worldwide where research and education in atmospheric science and glaciology are co-located. Accordingly, ACINN's research focus lies on aspects of mountain meteorology, earth-atmosphere interaction (with emphasis on snow- or ice-covered surfaces) and ice-climate relations.

The ACINN is devoted to basic research in the areas of weather forecasting, mountain meteorology, atmospheric composition, earth atmosphere interactions and ice-climate relations. Our research activity is largely supported by third-party funding. We investigate the atmosphere, the biosphere and the cryosphere – and their interactions – through theoretical/conceptional approaches, experimental means and numerical modeling.Detailed information on specific research themes can be found for each of the Research Units.
